2. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com2 Lack of Leadership It takes more than a talented and motivated team to make a successful project. Lack of leadership manifests itself in the team members suffering from:  Tunnel vision  Over-reliance on gut instincts  Repeated false starts in the project

Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com3 The Mid-Course Correction A change in project priorities throws the team into disarray This usually comes from a lack of understanding of the scope of the project When the engineers don’t understand the users’ and stakeholders’ needs, they build the wrong software  And they might not find out that there’s a problem until after the work is done!

4. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com4 The Detached Engineering Team There is an artificial wall between the people who build the software and those who need it.  The business people feel like the engineers are moving too slowly and don’t care about their needs  The engineers feel like they’re always shooting at a moving target because business people don’t know what they want

Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com5 Fixing Planning Problems Lack of Leadership, the Mid-Course Correction and the Detached Engineering Team are project planning problems  Use a vision and scope document to define the needs of the users and stakeholders  Use a project plan to keep every informed about how those needs will be met  Use risk planning to keep the plan realistic

Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com6 Padded Estimates Generate Distrust Programmers add extra time to their estimates  They may do this because of unknowns  Often they have been late in the past, and “know” that they will need extra time Project managers and senior managers quickly figure this out, and start to question individual estimates  And the programmers don’t have good answers!

7. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com7 Self-Fulfilling Prophecy A project manager under pressure simply imposes a deadline, and creates unrealistic estimates that meet it The team works nights and weekends to meet the deadline The project manager feels vindicated The team eventually gets frustrated and disillusioned

8. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com8 Fixing Estimation Problems Padded estimates and the self-fulfilling prophecy are estimation problems  Adopting a repeatable estimation process like Wideband Delphi can help fix them  By writing down assumptions, the team can handle risks without padding their time – and even avoid the risks altogether  It reduces padding and increases honesty through transparency, by letting the team correct each other in an open meeting

Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com9 Working Backwards From a Deadline Project managers approach a non- negotiable deadline for a project by working backwards  They shorten the tasks in the schedule or cutting them entirely until everything fits  When the schedule gets tight, any non- programming activities are cut and the software is released before it’s finished

10. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com10 Misunderstood Predecessors The project manger does not take the time to understand how tasks depend on each other Problems are discovered partway through the project one task can’t be started because it depends on another Delays cascade through the project, getting increasingly worse Some programmers are stuck waiting with nothing to do, while others work overtime

11. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com11 Fixing Scheduling Problems Working backwards from a deadline and misunderstood predecessors are symptoms of underlying scheduling problems  They can be avoided by adopting good planning and estimation practices and creating a project schedule  Schedule techniques like critical path analysis can help spot problems early on

12. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com12 Problems Are Found Too Late There are preventable defects in the software that aren’t caught until late in the project  The team may misunderstand a need, but that’s not discovered until delivery  Requirements may be missed or incorrect  The design may be difficult to use or fail to take all of the features into account

13. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com13 Big, Useless Meetings A project manager who has previously been burned by problems that were found too late is determined to avoid falling into the same trap  He calls a big meeting with everyone who could possibly have input  The meeting drags on for hours, without making any real progress  Eventually, everyone gives up and goes back to the way they did things before

14. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com14 The Indispensable “Hero” One “critical” person is seen as the clear top programmer, and all important work is sent through him  He may have a unique skill or experience  Sometimes he hoardes information so all tasks that rely on it must go through him  He is always working long hours – and causing bottlenecks

15. Applied Software Project Management Andrew Stellman & Jennifer Greene Applied Software Project Management http://www.stellman-greene.com15 Fixing Review Problems Problems that are found too late, big useless meetings, and the indispensable “hero” are problems which can be solved with reviews  Reviews can catch defects early, when they are cheaper to fix  A review meeting only includes the people necessary for the work to be done  Reviews – especially code reviews – can help the “hero” spread his expertise and knowledge
